Kerr said they'd consider expiring contracts, draft picks and young players. Going by that, the only players on the roster that Phoenix would be interested in acquiring would be:

AJ
Maxiell
Sheed
AI
Stuckey

They want to dump Stoudemire, not Shaq. So, something that could work is AI & Maxiell for Stoudemire & Barbosa. Phoenix gets a nice young PF in Maxiell and will have 40 million expiring over the next two seasons. We get a decent PF and an explosive guard who is actually accustomed to come off the bench. The intangible benefit is that Rip can now go back to the starting lineup.

5. San Antonio's desire to acquire one more big man (preferably a floor-stretching big man) to counter the Lakers and Boston is no secret. The surprise stems from the rumbles I've heard about Detroit free-agent-to-be Rasheed Wallace, he who is chief among the Pistons unsettled by the realization that big changes are undoubtedly coming in that locker room, having legit interest in joining the Spurs to team up with his 2005 NBA Finals nemesis Tim Duncan.
Don't see a real trade possibility here -- given that the Pistons are unlikely to take back anything other than expiring contracts for the expiring deals possessed by Wallace and Allen Iverson unless they have a chance to trade for someone like Stoudemire or Chris Bosh -- but it's something to file away for free agency
Another note for the future on Iverson: Detroit is far more unlikely than likely to find a workable trade home for Iverson after the Pistons' struggles since acquiring A.I. from Denver in the first week of the season, but I've heard multiple executives say there might be a better-than-expected market for the 33-year-old in free agency this summer as long as his demands are not exorbitant.
"There's never been a time where we're all touched by the economy at the same time," said one exec, suggesting that Iverson will appeal to a few teams just because of his ability to sell tickets.
